An issue was discovered on EDIMAX IC-3140W through 3.06, IC-5150W through 3.09, and IC-6220DC through 3.06 devices. The ipcamcgi binary contains a stack-based buffer overflow that is possible to trigger from a remote unauthenticated /camera-cgi/public/getsysyeminfo.cgi?action=VALUEHERE HTTP request: if the VALUEHERE length is more than 0x400 (1024), it is possible to overwrite other values located on the stack due to an incorrect use of the strcpy() function.

A vulnerability was found in Edimax IC-6220DC and IC-5150W up to 3.06. It has been rated as critical. Affected by this issue is the function cgiFormString of the file ipcamcgi. The manipulation of the argument host leads to command injection. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
